IpRestrictionModule - HTTP Error 500.19 - Internal Server Error

Question

After trying multiple configuration changes, I cannot seem to get past this error. This is a fresh install of Windows Server 2012R2, with all of the options selected under the ASP.NET/IIS modules and features selected. I'm using Visual Studio 2013, and the target framework is 4.5

I have also executed the following commands:

%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/handlers
%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/security/ipSecurity
%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/modules

Answer 1

Try adding

-commit:apphost

to the command, like this

%windir%\system32\inetsrv\appcmd.exe unlock config section:system.webServer/security/ipSecurity -commit:apphost

so that the unlocking is applied at the topmost (applicationhost.config) level instead of the lower web.config levels
